I hate posting negative news but haven't seen this so wanted to let some people to know who may have been waiting on picking up the new PSP Brite.  I had a fatty that I sold a while back and was going to buy the 2000 until I heard the new version was announced.  Anyway, there is a huge thread over on the Official Playstation forum about users having this problem.

Here are some pics from the thread (blown up obviously to highlight the problem).

Original Article about the issue from Joystiq:

Over on the official PlayStation forums, owners of Sony's revamped PSP Brite are in a tizzy over what many have reported as prominent screen interlacing during video playback and gameplay. The PSP-3000 uses a new high-contrast, low-latency screen that eliminates the ghosting/smearing associated with older PSP revisions, but appears to introduce a new issue of visible scanlines and notably jagged edges on moving objects. One poster provided comparison photos that illustrate the problem.

We unboxed our PSP Brite to test some games and see if we encountered the same problem. Sure enough, in both FMV and gameplay, there is a noticable offset between the two video fields comprising the on-screen image. The included Ratchet & Clank: Size Matters looks significantly more "pixelated" on the PSP-3000 versus on our PSP-2000, as did other games we tested, including God of War: Chains of Olympus and WipEout Pulse. Additionally, scanlines are visible simply when navigating the unit's XMB.

The problem is slightly less noticable when the new Wide Color Space option is turned off. We contacted SCEA for comment on this apparent hardware issue and were told that the company is "looking into this" and will get back to us as soon as possible. We'll update this post when we hear more. In the meantime, let us know in comments if you're experiencing similar issues with the PSP Brite.

I see a PSP-4000 on the horizon.

I wonder if this is a minor defect issue or just a side effect of the new screens?

this is why i love my psp-1000 and 60gb ps3. no corners are cut.

wow, thats horrible

When your walking or moving the character on the screen it makes all them interlacing lines, but when the character is standing still then everything's normal.

It's really not that bad, that picture is a little exaggerated because it's blow up so much, I rarely notice it

That ain't look good.

this issue about the interlacing on the psp 3000 screen is a little too exaggerated. it's not much of a big deal.

I was about to say this! -_-'

probably a bad batch.

That's exactly the same look i get when i hook up my Gamecube (interlaced games) to my computer LCD. As somebody said, no problem when still, but very noticable when in motion.
